'Application le. January 2K4, 192,4. Serial No. 688,278.

Toa/ZZ wzomz't may concern: y Be it lrnown that we, FREDERICK MACDON- ,V ALD 'Fnriieninvn and ARCHIBALD Fnrneiunvn,

subjects of the King of Great Britain, and residents ofthe city of Toronto, county of York, Province of Gntario, inthe Dominion of Canada, have invented lcertain new and useful improvements in Washing Machines,

as described in the following specification,

and illustrated in the accompanying drawings, that form part of the same.

rIhe principal objects of this invention are', toY completely enclose the mechanism for operating the :oscillating tub, thereby reducing the possibility of laccident to the operator, andl to devise an operatingk mechanism in which vibration is reduced to the minimum.

A still further object is to producel a mechanical structure Yof very simple construction and which is balanced inits operation.

The principal Vfeature ofv the invention consists in the novel construction and arrangement of parts, lwhereby an` oscillating. member for operating the tub, is operated by a pair of armsiconiiected to a rocker member andoperated byr a pair of eccentricy l. members oppositely disposed in Vat'balanced arrangement on a driving shaft, and whereby said parts are supportedv in a unitary structure. Y

In the drawings, Figure lisa side elevational view of our improved washing machine.

Figure '2 is an enlarged perspective skeleton view of the tub driving mechanism, the casing being shown in its relative position thereto in dotted lines. Y

Figure 3 is a sectional detail showing the roclrer shaft for oscillating the tub.`

Figure 4; is anf enlarged vertical sectional view through they eccentric member.

Figure is an elevational detail showing the preferred arrangement of the driving motor.

On reference vto the drawings, the frame structure of the washing machine for supporting the tub` may, be, of anydesirable shapeV but is here shown as a rectangular kframe 1 supported-on` legs 2 and to this frame is secured at one corner of its outer side a vertically arranged casing 3.

rEhe lower vportion of the casing 3 is of cylindrical form and issecured to the corner upright i of the frame by integral lugs 5.

Intermediate of the height of the casing it is formed with a horizontal extension 6 from which a lug 7 projects downwardly and is secured to the top bar 8 of the frame. The upper end of the casing tapers to a reduced cylindrical portion 9 in which is carried the upper journal 10 of the vertical drive shaft 11.

`A cap 12 is secured to the lower end of the casing 3 and in this cap is journalled a worm wheel 13 in which the bottom end of the shaft 11 is stepped.

ri worm shaft 14 is journalled transversely of the cap'12 and is provided with apulley 15V on its outer end to which the motor 16 is connected by a suitable belt.

ltwill be noted that the motor is carried on a hinged support 17 so vthat the weight of the motor is used to apply and maintain a uniform tension on the belt.

A pin 13 is mountedtransversely of the horizontal extension 6 adjacent to Vits outer endand onthis pin is rotatablV mounted the rocker member 19. This roclier arm is provided with a notch 2O in its forward side which is engaged byV an eccentric lever 21 to slide it on the pin 18 so as to move the clutch member 22 upon the inner end thereof into engagement with a clutch member 23 journalled in the inner side of the casing.

The member 23 is provided with a key stone shaped member having dove tailed sides to engage and support the correspondingly recessed holder of the tub 211.

A correspondingly pivoted support is arranged at the opposite side of the frame to support the other side of the tub.

Upon the vertical .shaft 11 is mounted a sleeve member 25 held in place opposite the horizontal portion 6 of the casing and upon the upper end of this sleeve is formed an eccentric sheave 26 and upon the lower end formed with forks 34 at the outer ends to extend each side ot the ends of the rocker member 19.

Pins 35 with ball centres are secured in the forks 3l and extend through the ends ot the rocker 19 which are shaped to allow latitude of lateral movement between the rocke and the connecting rod.

r1`he upper end of the casing 3 is provided with a notched flange 3G upon which the flange 3T ot the wringer support casing 3S is adapted to rest. rllhe wringer casing is provided with a reverse gear 39 of a well known construction.

In the operation of this washer th-e motor 16 operates the worm and through the worm wheel 13 rotates the main shaft 11. The worm wheel may be adjusted in relation to the worm by means ot the adjustable ecccn tric step bearing el-O.

The eccentric members QG and QT are formed ot' a single castinfT and are secured to the shalt by a suitable pin in the connecting sleeve. Vthe rotation ot the eccentrics around the avis of the shat't imparts a reciprocating movement to the rods and being arranged diametricall5v opposite the one to the other the action ot' each rod operates to pull upon the opposite ends of the rocker member alternately. The thrust against the opposing member equals the pull ot the other in such a manner that the shaft is always balanced and requires no support adjacent to the eccentrics and does not spring.

rIhis eccentric arrangement renders the operation extremely smooth and free from vibration and the tub is oscillated without the use oi springs and in an exeeedinglv lquiet manner.

It is very important to note that the entire operating` mechanism is enclosed within the uuitarj: casing. rl`his obviates the dangers ot accidental injur)v to the operator and a machine ot cxtremel)T attractive appearance is produced.

duit we claim as our invention is 1. In a washing machine, the combination with a rigid frame and an oscillating tub, ot a rocker member disengageablvv connected with the tub, means for moving said rocker member into and out ot operating contact with said tub, a vertical driveshatt, a pair et" sheaves rigidlvy arranged upon a connecting sleeve and placed in diamet-ricallv or posed relation the one to the other, the said sleeve being rigidlyv mounted on the drive shalt, rings rotatablyY mounted on said sheaves, forked connecting rods directly pivoted at one end to said rings and at the other end to the opposing ends of the rocker member.

2. In a washing machine, the combination with a rigid :trame and an oscillating tub, of a rocker member connected with the tub, a vertical drive shaft. a sleeve adjustably secured to said drive shat't and having 'lormed integral therewith at opposite ends thereot' a pair ot eccent-rics arranged in diametricallv opposed relation, the lower eccentric having a projecting` flange, a ringl on the lower eccentric resting upon said flange, a ring encircling the upper eccentric and having a liange at its upper edge resting on the eccentric, and formed connecting rods secured at one end to said rings and at the other end to the opposite ends ot the rocker member.

3. In a washing machine, the combination with a rigid 'trame and an oscillating tub, ol' a rigid casing having a horizontal portion and a vertical portion. a liournal pin rigidlv supported in the horizontal portion of the casing in axial alignment with the tub.y a clutch member connected to the tub and oscillating on said pin and having an external bearing in said casing, a rocker member rotatably mounted on said pin and capable ot' movement longitudinally thereof and having a clutch member to engage the aforesaid clutch, means for moving said rocker member on said pin into and out ot clutch, a drive shaft arranged in the vertical portion o said casing, and means connected with said rocker member and operativelvv connected with said drive shaft to rock said member on said pin.

4t. In a washing machine. the combination with a rigid frame and an oscillating tub mounted on said frame, ol a rocker member slidablv mounted and connected with the tub, a cylindrical shaped casing vertically arranged and rigidly supported on the frame and having` a horizontal extension projecting opposite the axis ot the tub.

mannall Y ooerated means mounted on said extension for disconnecting said rocker member from the tub, rigid connecting rods for oscillating the tub arranged within the horizontal extension` a vertical drive sha'tt arranged in the cylindrical casing and operativelv connected directl)v through said connecting rods to the rocker memlwr, and means tor driving said vertical shalt.
